' DOORCHECK Filed larch 3, 1924 Patented June 16, 1931 P ENT CHARLES W. BECK, TOLEDO, OHIO, ASSIGNOR, BY MESNE ASSIGNIZIENTS, TO ALC'ET ELECTED PRODUCTS CORPORATION, OF NEI/V YORK, N. Y.,'A CORPORATION OF DELA- WARE Application filed March a, 1924, Serial No. 696,619.

This invention relates to door checks such as are used for limiting the opening of doors of motor vehicles and consists of certain novel features of construction and combina- 5! tion of parts as hereinafter set forth.

In the accompanying drawings Figure 1 is a side elevation of a door check embodying my invention applied to adoor of a motor vehicle:

Figure 2 is a fragmentary elevationof the door check shown in Figure 1; a I I Figure 3 is an elevation of a slightlymodified form of door check; 5

Figure 4 is a sectional view taken on line H of Figure 3;

Figure 5 is a fragmentary elevation of an- 7 otherform of door check; 1 4 Figure 6 is asectional View taken on line 6-6 of Figure 5; e j

Figure 7 is an elevation of another modification.

Referring now to the drawings in which like characters of reference designate correw sponding parts throughout'the several views,

the numeral 1 designates a door hingedly connected to a post 2, preferably of a vehicle body. v T V For checking the outward'swinging movement'of the door, I preferably provide a strip 3 of resilient material such as softrubber having transversely extending openings 4 at the opposite ends thereof. Extending through these openings are brackets 5 which are preferably U-shape in configuration and have apertured laterally extending feet '6 that are secured respectively to the door 1 and post 2 as shown in Figure 1 of the drawings. Thus, with this construction, the door will be yieldably checked when swung outwardly.

In the process of construction, the rubber p strip may be molded with the openings 4 for receiving the'bra kets and th'e'latter subsequently pushed or pulled through the open ings. If desired, the brackets may be placed into a suitable mold so that the rubber may be molded about the same to provide the finished door check.

In Figure 3 I have shown a slight modification in which the resilient strip 6 is provided with a longitudinally extending opening 7 that connects into the transversely extending openings 8 at the ends of the strip. Located in the longitudnally extending opening 7 is a suitable non-stretchable element such as a chain 9 that is preferably connect-- ed at its-opposite ends to the U-shaped por tions 10 of the brackets 11. This chain is preferably of sufficient length to permit the strip 6 to stretch a limited amount before the chain becomes taut, hence, the strip will yieldably check the outwardly swinging movement of the door to a pre-determined point whereupon the chain will form a positive stop for limiting the outward swinging movement of the door. t 1

In the process of construction, the openings 8 and!) respectively may be formed in the strip, whereupon the metal parts may be assembled by securing one end of the chain to one of the brackets and then flexing one end of the strip to substantially align the opening 9 with a portion of the opening 8. The free end of the chain is then attached to a suitable tool (not shown) for pulling the chain through the openings 8 and 9, the strip being flexed atthe other end in a similar manner to permit the tool and chain to be pulled through. The free end of the chain is then secured to the second bracket and the latter is inserted in the opening 8. If desired, the rubber may be molded upon the chain and brackets after the latter have been connected to the chain and any suitable means, such as paper, may be used to cover the chain to prevent the plastic material adhering to the chain during the molding operation. I

In Figure 5, I have shown still another modification 'in which a coil spring 20 is referably used instead of a resilient strip to yieldably check the door". As shown, the ends of the spring 20 are secured to the U- shaped portions 21 of the brackets 22. The chain is preferably enclosed in a suitable casing or covering 23 of flexible material such as leather, canvas and the like which is also secured to the brackets 22. In use, this con struction will function'substantially the same as that shown in Figure 1 of the drawings with the exception that the covering 23 will constitute a stop for limiting the outward swinging movement of the door.

In Figure 7 I have shown another modification in which a coil spring 24 surrounds a chain 25 and is enclosed in a. suitable flexible covering 26. To provide a strong and durable construction, the opposite ends of the chain 25, spring 24 and covering 26 are all connected to the U-shaped portions 27 of the brackets 28 which are secured respec tively to the door and post as shown in Figure 1 of the drawings. This construction will function substantially the same as that illustrated in Figure 2 of the drawings.

From the foregoing description it will be readily. apparent that I have provided a strong and durable and yet simple and inexpensive device that may be easily and quickly installed for yieldably and gradually checking the movement of doors, gates, windows and the like. so that the ordinary shocks and jars due to the sudden checking of such elements is obviated entirely. V

\Vhile it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, l desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. A door check comprising a pair of brackets, ayieldable member connected thereto, and means extending between said brackets for limiting't-he yielding movement of the yieldable member.

2. A door check comprising apair or brackets, a yieldable member connected thereto, and a. member extending longitudimany of said yieldable member and connected to said brackets for limiting the yielding movement of said yieldable member.

3. A door check comprising a pair of at taching brackets, a yieldable member termi nally connected thereto, and a. member also terminally secured to said brackets "for liiniting the yielding movement'of said yieldable member.

4. A door check comprising a pair of substantially U-sha-ped attaching brackets, a yieldable member terminall secured thereto, and means extending longitudinally of said member for limiting the yielding move ment thereof.

5. The combination with a stationary member and a movable member, of yieldable means extending between said members for gradually checking the movement of the movable member, and means also extending between said members for limiting the yield ing movement of the yieldable means.

6. The combination'with a stationary membar and a movablemember, of brackets secured respectively to said stationary and movable members, a yieldable member connected to said brackets for gradually checking the movement of the movable member, and means also connected to said brackets for limiting the movement of said movable member.

7. The combination with a stationary mem ber and a movable member, of brackets secured respectively to said stationary and movable members, a yieldable member connected to said brackets for gradually checking the movement of the movable member, and a member extending longitudinally oi said yieldable member and also connected to said brackets for limiting the movement of said-movable member.

8. The combination with a stationary member and a movable member, of brackets secured respectively to said stationary and movable members, a yieldable member terminally .conn'ectedto said brackets for gradually checking the movement 01": the movable member, and a non-stretchable member terminally connected to said brackets forl-iinit ing the yielding movement of said yieldable member.

9. A door check comprising a pair of brackets, 21. yieldable member extending between said brackets, and a non-stretchable member extending between said brackets for limiting the yielding movement of the yieldable member.

10. A door check comprising a pair of brackets, a flexible member extending between said brackets, and a non stretc-hable member extending longitudinally of said flexible member and secured to said brackets.

. 11. A door check comprising a pair of anchorage members, and a pair of telescopically arranged members connected to said anchorage members, one of said telescopically arranged members being yieldable, and the other of said telescopically arranged members being non-stretchable for limiting the yielding movement of the yieldable member aforesaid.

12. The combination with a swinging door and its frame of a flexible, resilient link connecting said door and frame, and adapted to attain a condition of initial strain when the door has reached a relatively-wide opening, said link being-essentially composed of vulcanized soft rubber compound. I

13. The combination with 'a. stationary member and a movable member, of means for gradually checking the movement of the movable member, comprising a yieldable member connected to said stationary and movable members, and a non-stretchable member connected to said stationary and movable members for limiting the yielding movement of said yieldable member.

In testimony whereof I aflix my signature.
